Notes
1.0 General Warnings
WARNING!
DO NOT USE THIS PRODUCT OR ANY AVAILABLE OPTIONAL EQUIPMENT WITHOUT
FIRST COMPLETELY READING AND UNDERSTANDING THESE INSTRUCTIONS AND
ANY ADDITIONAL INSTRUCTIONAL MATERIAL SUCH AS OWNER’S MANUALS,
SERVICE MANUALS OR INSTRUCTION SHEETS SUPPLIED WITH THIS PRODUCT OR
OPTIONAL EQUIPMENT. IF YOU ARE UNABLE TO UNDERSTAND THE WARNINGS,
CAUTIONS OR INSTRUCTIONS, CONTACT A HEALTHCARE PROFESSIONAL, DEALER
OR TECHNICAL PERSONNEL BEFORE ATTEMPTING TO USE THIS EQUIPMENT OTHERWISE, INJURY OR DAMAGE MAY OCCUR.
ACCESSORIES WARNING
Invacare products are specifically designed and manufactured for use in
conjunction with Invacare accessories. Accessories designed by other
manufacturers have not been tested by Invacare and are not recommended
for use with Invacare products.
INSTALLATION WARNING
The procedures in this manual should be performed by a qualified technician.
After any adjustments, repair or service and before use, make sure that all
attaching component parts are secure.
DO NOT install the Invacare Matrx Elite assembly onto back canes with an
outside diameter greater than 1-inch or less than 3/4-inch. Otherwise, injury
or damage may occur.
The mounting position of the Invacare Matrx Elite is directly related to the
chair's stability. When the Invacare Matrx Elite is added to a TILT and/or
RECLINING chair, it may cause a decrease in the chair's stability. It may be
necessary to reposition the FRONT CASTERS, REAR WHEELS, BACK ANGLE,
TILT-IN-SPACE, RECLINE POSITION and/or SEAT DEPTH before use. Use
extreme caution when using a new seating position.
When a Matrx Elite is added to a TILT and/or RECLINING chair, a RIGIDIZER
BAR or CROSSBAR must be present to stabilize the back canes.
Ensure the Invacare Matrx Elite is properly secured to the wheelchair before
using. Otherwise injury or damage may occur.
16
WARNING!
Skin condition should be checked very frequently after the installation of any
new seating system.
Your therapist and physician should be consulted if you have any questions
regarding individual limitations and needs.
Working with your therapist, physician, and equipment supplier is the best way
to assure that a seating choice matches your individual needs.
As the needs of the individual become more complex, the seating evaluation
becomes more important.

By changing the orientation of the Mounting Plates on the Cane Clamps, the
assembly can be reconfigured* to provide a more forward mounting position for
the back if desired (up to a maximum 2.5” (64mm) forward offset - see Figure 2)
WARNING! When establishing the mounting position for the Matrx Elite
HD back, ensure the stability of the wheelchair is not compromised.
Adjusting the forward and aft position of the backrest will alter the user’s
center of gravity within the wheelchair. A recessed back position can
significantly reduce the rearward stability of the wheelchair. Similarly, a
more forward back position will reduce the wheelchair’s forward stability.

NOTE: For wheelchairs with short back canes, it may be
necessary to install Posture Back Cane Replacements
(PBCR’s). The PBCR’s are designed to replace existing push
handles or cane extensions on standard 1” (26mm) back
posts. The Cane Clamps can be mounted directly onto the
replacement back canes in order to allow proper installation
of the Matrx Elite HD back. Cane Replacements are available
from Motion Concepts (part#-TRX2810).

With the back properly installed on the wheelchair, adjust the cord length
so that it hangs at approximately a 45° angle along the back pan (this will
allow the release mechanism to operate more effectively). If necessary, cut/remove
excess cord to eliminate any risk of entanglement. Once adjusted, combine
the loose cord ends into a single knot to prevent the cord-lock from slipping.
(Note: if the cord length was modified, carefully melt the ends of the cord to
prevent fraying)

Matrx Elite HD backs are available in four widths: 21”(53 cm), 22”(56 cm), 23”(58 cm) and
24”(63 cm); and two standard heights: (16" (41cm) and 20" (51cm)). Due to variances that
exist between different wheelchair manufacturers, the depth of the mounting pins may
require some adjustment to properly fit the Matrx Elite HD back onto the wheelchair
back canes (see Step 8). Two sets of depth adjustable pins are supplied with every back:
Standard Pins (x4) and Long Pins (x4)*. Our standard pins come factory installed and
are suitable for most typical wheelchair configurations. Long pins are designed to allow
installation onto back canes that are up to 1" (25mm) wider than the width of the actual
backrest.
Example: 22" (56 cm) Matrx Elite HD fits:
22" (56 cm) wheelchair seat frame (back cane width) = Standard Pins
23" (58 cm) wheelchair seat frame (back cane width) = Long Pins
*NOTE: when exchanging mounting pins, the Pem-Nut Backing Plates (not shown)
must be re-aligned with the new mounting pins in order to complete the installation.

To adjust the mounting pins:
i) With the back secured in place on the wheelchair, determine the
amount of adjustment required for each mounting pin (see below).
ii) Remove the backrest from the wheelchair and use the wrench
provided to loosen each flange nut. (If necessary, replace the standard
mounting pins with long mounting pins).
iii) Adjust the mounting pin depth (clockwise to shorten/counter-clock
wise to lengthen) so that a minimum gap of 1/8" (3 mm) exists between the
top of the pin and the mounting plate. Re-tighten each flange nut to
secure the pins in place. (ensure pins do not rotate when tightening the
flange nuts- NEVER use loctite on mounting pin hardware).
WARNING! Ensure all flange nuts are fully tightened; Failure to do
so may cause damage/cracking in the back pan
Standard Mounting Pin
Verify that the overall fit and alignment of the back is correct (make
adjustments as needed).
10 Fully secure the Cane Clamp Screws onto both back posts, and tighten
the set screws to ensure the mounting plates do not slip or rotate.
11 To best determine the optimal depth & recline settings for the back, the
user should be seated in the wheelchair. While seated, loosen the depth/
recline screws on the mounting plates and adjust the back to the desired
depth and recline angle. Re-tighten all screws to lock the back in position.
Ensure that the depth/recline adjustment for the back is made
symmetrically* on the left & right mounting plates.
!
PLEASE NOTE
The vertical score lines on the mounting
plates are designed as a point of reference
to assist with symmetrical mounting (see
image below). Since the back can be
mounted in a rotated (reclined) position
if desired, it will not always be mounted
parallel with these vertical lines.
